Application filed. August 16, 1909. Serial No. 512,990. I

,To all whom it may concern:

Be it knownthat I, NELLIE W. Lown,a

citizen of the United States, residing atf Qmaha,in the county of Douglas and State 5 of Nebraska, have invented certain new and useful Improvements in Incinerating Receptacles and Chutes, of which the following is a specification.

T1118 lnventlon relates to an inclnerat ng foruSB inhos itals.

The object of the invention is to provide, for the use of these institutions, means for the handling and destruction of refuse, such parts after they have been used, so that in- "fection may beeliminated.

With these objects in view the invention discloses a novel combination and arrangement of parts as described herein, pointed out by the appended claims, and as illustrated .in the accompanying drawing, it being understood that changes in form, size, proportion and minor details may be made within the scope of the claims without departing from the spirit "or sacrificing any of the advantages of the invention.

In the drawing, forming a part of the application, Figure l is a broken away, side view, in section, of an incinerating receptacle and chuteembodying my invention. Fig. 2 is a front view showing the parts illustrated by Fig. 1. Fig. 3 is an enlarged detail, beinga side view, partly in section, of the firing disk or panand fuel pipe. Fig. 4a is a plan view, partly broken away, showing the partsillustrated by Fig. 3, a bifurcated, annulargrate beingadded. Fig. 5

.fied incinerating receptacle, believed to be within the scope of the invention.

The herein described incinerating receptac'leand chute may be constructed to ad- ,vantage, of galvanizediron or other sheet receptacle and chute, adapted particularly convenient and efiective manner.

is a vertical, side view, insection, of a modi-- metal, but other metallic.constructionsmay be employed, if desired.

Referring to the drawing, the numeral 1 designates an inclneratin receptacle comprising a metalhc cylindr cal casing 2, having a peripheral rib 3near its bottom. A

door opening 4 formed in said receptacle is closed when desired by a hinged door 5. The door 5 is provided with suitable fastenings 6 and with a rib 3 corresponding to rib 3 of the casing 2. A bottom 4' closes the lowerend of the casing. Casing 2 is provided with a dome 7 having a smokepipe 8 communicating with chimney 9. The upper part of the dome is provided with a housing-frame 10 in which may be seated the cutoff or sliding-plate 11, these parts being inclined upwardly and rearwardly in the direction of pipe 8;.and pipe 8 is provided with a transverse housing-frame 12 in which is seated sliding-plate 13. I provide the secondary dome .14: disposed above and communicating with dome 7, and having at its upper terminal a horizontal housingframe 15 in which may be seated the slidingplate 16.

At 17 is indicated an upright chute, and it may traverse the several floors 33 of a building, its upper terminal communicating seated sliding-plate 20. In the chute, at a suitable height above each floor, is provided an intake opening 21, stationary spots 22 being secured upon the wall of the chute, adjacent these openings, and hinged lids 23 are employedtocompletely and effectively make closures of ,the spouts, and dry or saturated fabrics and other similar refuse incident to the care of invalids and usually removed from hospitals to be destroyed, may

be conveniently disposed of by passing the H same through the intakes mentioned, and as will be seen, the refuse will be destroyed in a Said refuse will fall within receptacle 2, slidingplates 11 and 16 remaining,in withdrawn positions at all times except when the contents of the receptacle are burned, adequate means for the destruction of this refuse to be presently described. 2

Chute 17 may be located in any desired part of a building, and of course may pass within an operatlng room, toilet or nurses room, as may be desired. Intakes 21 and sliding-plate 20 are normally keptclosed. Any suitable construction may be employed for the housing-frames mentioned, in which the plates may slide; these frames or sections, however should have an area greater than the pipes or domes wherein they are mounted, and the sliding-plates have an area greater than the openings which they cover, so that a suitable and effective control may be obtained of the passage ways, by use of the sliding-plates. It will be understood that the herein described devices are operative without regard to the number of floors of a building, and the intakes and their connections are so constructed that the use of one does not interfere with the simultaneous use of others.

I provide the annular, bifurcated grate 24 having a diameter substantially equal to the interior of casing 2, and adapted to have a seating in the receptacle upon the interior ridge formed by grooves 3 and 3, and since it has a two-part construction, it may be conveniently deposited within the casing when the parts are assembled.

At 25 is indicated a shallow firing pan or disk, adapted to have a seating upon the grate midway of the cylindrical wall of the receptacle. At 26, secured exteriorly of and upon the wall of the receptacle, is indicated an oil cup having a downwardly inclined feed pipe 27 communicating with pipe-section 28, the latter being employed for convenience in assembling the parts, the ends of pipe-section 28 and the terminal of pipe 27, preferably, being threaded to connect with coupling 29, and with stem 30 of pan 25.

Receptacle 1 may be located to advantage in the basement of a building, and when sliding-plates 11 and 16 have been closed, sliding-plate 13 being withdrawn, the devices described will be adequate to destroy damp or wet bandages or similar cast-off material. The firing-pan may be conveniently supplied with oil from the supplycup, and damp or wet fabrics will become sufiiciently saturated with oil to cause incineration thereof.

In practice, the pan is supplied with oil before the refuse is deposited, and it thereby becomes saturated as mentioned. At the time and while the refuse is burning there will be no oil in the supply cup, and danger from fire is eliminated so far as the exterior cup is concerned, and only a suflicient amount of oil is used in the firing-pan to cause a thorough combustion of the refuse. In practice it has been found that galvanized iron is a preferred material for constructing the incinerating receptacle, but in large institutions where the refuse is very considerable, there is no objection, and it may be an advantage to use heavier material, for the heat'generated in such cases would be more intense, moreoil being required.

Sliding-plate 20 remains closed at all times except when it is desired to disinfect the chute. In order that the chute may be kept in a sanitary condition, certain devices are employed now to be explained. To disinfect the chute and parts connected therewith, a time is chosen when no refuse is in receptacle 1. Sliding-plate 20 may be withdrawn for this purpose, sliding-plate 13 and lids 23, of course, being closed, and plates 11 and 16 are withdrawn. 7 A preparation of sulfur mixed with oil or other suitable disinfecting material is placed in firingpan 25 and is ignited, door opening 4: being available for access thereto. By reason of the draft thus created the fumes of the burning disinfectant will readily fumigate and ventilate the entire chute and its connecting parts.

By the construction shown, it will be noted that domes 7 and 14 and chute 17 have different diameters, the area of a lower compartment through which material passes being greater than an upper compartment, and this is a desired feature, to prevent the deposit upon the walls of'these compartments or of lodgment therein of any of the material.

I have shown a portable incinerating receptacle 31, useful particularly in connection with one-story hospital buildings. It consists of the cylindrical casing 2- having a peripheral groove and door and bottom, substantially as already described, together with grate 24 supported upon the annular ridge as described, and upon the grate is supported the firing-pan 25, with a fuelcup 26 and its connected pipes 27 and 28, the same as mentioned. Refuse may be deposited in receptacle 31, and when deposited out-of-doors, the oil-saturated refuse may be ignited, and the cylindrical wall of the casing will operate to provide a draft, cover 32 being removed at this time.

Having fully described my invention, what I claim and desire to secure by Letters Patent is,-

1. In an incinerating apparatus for destroying germ bearing articles, the combination with a building and its chimney, of a receptacle adapted to retain said articles while they are being consumed, an article i receptacle, a firing pan located centrally the receptacle, and means leading from the sure at each floor for said openings, said I for feeding combustible oil thereinto, said 10 openings permitting the passage of the germ pan and said grating together serving to hearing articles into said chute. support articles to be consumed.
